you feel rested before you begi
ndriving and
during yourj ourney. Always take breaks in
good time and regularly, especially during
long journeys. Otherwise, you may fail to rec-
ognise dangers in time, cause an accident and
injure yourself and others.
General notes ATTENTION ASSIST helps you during long,
monotonous journeys such as on motorways
and trunk roads. It is active in the 80 km/h
to 180 km/h range.
If ATTENTION ASSIST detects typical indica-
tors of fatigue or increasing lapses in con-
centration on the part of the driver, it sug-
gests taking a break.
ATTENTION ASSIST assesses your level of
fatigue or lapses in concentration by taking
the following criteria into account:
R your personal driving style, e.g. steering
characteristics
R journey-related parameters, e.g. time of
day, length of journey
The functionality of ATTENTION ASSIST is
restricted, and warnings may be delayed or
not occur at all:
R if the road condition is poor, e.g. if the sur-
face is uneven or if there are potholes
R if there is a strong side wind
R if you have adopted a sporty driving style
with high cornering speeds or high rates of
acceleration
R if you are predominantly driving slower
than 80 km/h or faster than 180 km/h
R if you are currently using COMAND APS or
making a telephone call with COMAND APS
R if the time has been set incorrectly
R in active driving situations, such as when
you change lanes or change your speed Warning and display messages in the
multifunction display If ATTENTION ASSIST is active, you will be
warned no sooner than 20 minutes after your
journey has begun. You then hear an inter-
mittent warning tone twice and the
Atten‐ tion Assist: Drowsiness detected mes-
sage appears in the multifunction display.
X Activate ATTENTION ASSIST using the on-
board computer (Y page 238).
Symbol :appears in the multifunction
display.
X If necessary, take a break.
X Press the abutton to confirm the mes-
sage.
On long journeys, take regular breaks in good
time to allow yourself to rest properly. If you
do not take a break, you will be warned again
after 15 minutes at the earliest. This will only
happen if ATTENTION ASSIST still detects
typical indicators of fatigue or increasing lap-
ses in concentration.
ATTENTION ASSIST is reset and starts
assessing your tiredness again when you con-
tinue your journey if:
R you switch off the engine.
R you take off your seat belt and open the
driver's door, e.g. for a change of drivers or
to take a break. Driving systems
